Prayer times across the United Kingdom

WhiskAI uses the Muslim World League (MWL) standard for all 30 UK cities — Fajr at 18° below the horizon during dawn twilight, Isha at 17° below the horizon during dusk twilight, Asr calculated by the standard Shafi'i shadow rule. MWL is the convention adopted by the Muslim Council of Britain, the Council of Mosques in many British cities, and the majority of British mosques across all four nations. We selected MWL for consistency rather than splitting calculations by city or community; a Hanafi Asr override is available via the calculation toggle on each city page for readers following that school.

British prayer times exhibit dramatic seasonal swing because of the UK's high northern latitude. London sits at 51.5°N, Manchester at 53.5°N, Glasgow at 55.9°N, and Aberdeen at 57.1°N. At these latitudes the sun's path makes a shallow angle with the horizon in summer, stretching dawn and dusk twilight. In late June, calculated Fajr arrives between 02:00 and 02:30 across British cities while Isha falls between 22:30 and 23:30 — a Fajr-to-Isha window of more than 20 hours. Conversely, December produces Fajr around 06:30 and Maghrib before 16:00. The 30-day Ramadan fast can range from 11 hours in winter to 19 hours at midsummer depending on the year.

Yes — every active British mosque we have surveyed publishes iqamah times that delay congregational prayer beyond WhiskAI's calculated adhan times. Typical delays are: Fajr iqamah 25 to 30 minutes after adhan (giving worshippers time to wake, perform ablution, and travel); Dhuhr, Asr, and Isha iqamah 10 to 15 minutes after adhan; Maghrib iqamah 5 to 10 minutes after adhan because the window itself is short. Iqamah varies by mosque even within the same city — London Central Mosque, East London Mosque, and Finsbury Park Mosque each publish their own schedule. For congregational prayer, always check your local mosque's website or noticeboard rather than relying on WhiskAI's calculated adhan-only times.

Several minorities of British mosques follow alternative calculation methods. The most common alternative is the University of Islamic Sciences (Karachi) method, used by some Pakistani-tradition mosques in Bradford, Birmingham, and Greater Manchester. Karachi uses 18° for both Fajr and Isha, producing slightly later Isha than MWL. A smaller number of mosques follow the Egyptian General Authority of Survey method (Fajr 19.5°, Isha 17.5°), particularly in communities with strong Egyptian or North African heritage. A handful of northern British mosques apply seasonal high-latitude adjustments to moderate the extreme summer Fajr that pure astronomical calculation produces. WhiskAI defaults to MWL because it is the most widely adopted convention; consult your local mosque if your community follows a different method.
